Fourteen preterm infants 30-32 weeks gestational age between 2-9 days postnatal age were tested in a randomized cross-over design to test the effect of Kangaroo Care on heart rate variability responses to heel stick. Heel stick is the most common painful procedure and pain impairs neurologic and immunologic functioning. Heel sticks occurred at 11:00 am for medical tests. Infants were randomly assigned to KC on Day1 then incubator care on Day2 or incubator care on Day1 then KC on Day2. Infants were in the incubator from 10:00-11:30 and had heel stick in the incubator; on the KC day, infants were held skin-to-skin from 10:00 -11:30 and had the heel stick done in KC. For both groups HRV recording using an ANSAR1000 began at 10:45 am and continued through heel warming, heel stick, and recovery phases. ANSAR sampled heart rate continuously and calculated low frequency (LF), high frequency (HF), and low frequency/high frequency (LF/HF) ratio every 22 seconds based on R-to-R intervals. GEE model tested treatment effects. On KC day as compared to incubator day, HR was lower during baseline and heel stick phases, and higher during heel stick than any other phase. On the KC day as compared to incubator day, LF and HF were higher during baseline, LF was higher during heel stick, and LF/HF was lower during recovery. Comparing the phases, LF and HF were higher during heel stick than other phases on both KC and incubator days. The LF/HF ratio was lower during heel stick than other phases on both days. Heel stick was more painful than other phases of the procedure and reactivity was higher during KC than in the incubator, suggesting better autonomic responsivity during KC. The lower HR and LF/HF ratio (parasympathetic dominance during KC) suggests a comforting role for KC in the management of pain.
